The correct answer is that mammals use a closed, double loop , four chambered heart as a circulatory system of the body.
The circulatory system of mammals is closed system that consists of four chambers, two articles and two ventricles. The deoxygenated blood comes into the heart from one loop and the oxygenated blood from other loop from the heart is circulated to the whole body. This is called as double circulation.
Answer:
The correct option is A
Explanation:
To determine if water temperature has an effect on weathering of sedimentary rocks, different number (perhaps three) of identical sedimentary rocks should be obtained and then individually placed in different water temperatures (with at least one of the "water volumes" used for each having a temperature close to the room temperature so as to be used as the control).
Thus, each of the identical sedimentary rock can be broken into three and placed individually; as in one part of the rock in 20 °C of water (control), another part of the rock in 40 °C and another in 60 °C of water.
This above procedure should be repeated for the remaining two other identical sedimentary rock to confirm if there is any effect.
Answer:
The correct answer is amino acids.
Explanation:
The organic compounds, which associates together to produce proteins are known as amino acids. The proteins and amino acids are the building blocks of life. At the time of the digestion or dissociation of proteins, amino acids get left. A huge ratio of the muscles, cells, and the tissues are formed of amino acids, which shows that they conduct various essential functions of the body like providing cells their composition.
Answer: receives the thermal energy
Explanation:
The cryosphere can be defined as the land which is covered with the surface of ice in the solid form in the form of sea ice, river ice, snow, ice glaciers, ice sheets, frozen water, and others. When the ice on the land receives the thermal energy from the sun or any other source like radiation then it melts into water and it becomes the part of the water body in the form of the hydrosphere.
